Been there, done that.

Both without restrictor, and with restrictor (3 different sizes)

Generally accepted nowadays as a waste of time and money.

Too much oil in the rocker box/valve cover is one result, oil smoke out of 
the exhaust is another, and a drop in oil pressure, even on a known good low 
mileage engine is a third.

The rocker arms were bushed with oilite phosphor-bronze bushings, at great 
cost, but they wore out, as did the NOS original Leyland rocker shaft  in under 
20k miles, even with the oil feed hose - I put it down to poor heat treatment 
of the shaft.

I replaced the rocker arms with Harland-Sharpe Roller Rockers (of mild lift) 
- this is a road car, and the shaft with a Ted Schumacher supplied tuftrided 
rocker shaft.

After another 20k miles even the tuftrided shaft is just starting to wear, 
although the roller rockers are fine, and that's without the oil hose! 

My engine has always sent plenty of oil up to the rocker shaft, even without 
the oil feed hose. 

The oil feed hose is where it belongs - in the trash.

I have read of similar experiences from many Triumph 6 cylinder owners over a 
long period of time.

YMMV.
